We propose a layered space-time equalization (LSTE) architecture for multiple-input multiple-output (MIMO) frequency selective channels, based on the MIMO delayed decision feedback sequence estimation (MIMO-DDFSE) scheme. At each stage of detection, the MIMO-DDFSE is employed to tentatively detect a group of selected signal streams, and among them a sub-group of the best signal streams in the MMSE sense are output and are cancelled from the received signals. It is shown that this structure outperforms the previously developed LSTE structure based on the multiple-input single-output decision feedback equalization (MISO-DFE) scheme
